The thick pile fabric used for these bulky slipper socks is made of 19.5 micron extra fine merino wool. The tenderly soft texture of the material gives the highest quality to this item. Extra fine merino wool comes also with heat-retaining, moisture-wicking, moisture-absorbent, anti-odor and anti-bacterial properties. As the fabric is pre-shrinked, you can wash this item at home.
* Use a laundry bag when washing. Line dry in shade with the opening upward.
